It seems to me that this description should consider that an object's properties may be ordered since ES6 but for backwards compatibility this cannot be relied upon.

"It should be noted that a Map which is a map of an object, especially a dictionary of dictionaries, will only map to the object's insertion order. In ES6 this is ordered for objects but for older versions of ES, this may be random and not ordered."

Sorry it took so long to get to this. I've updated the page as per your suggestion: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map

As MDN is a wiki, also consider to make such edits yourself in the future :)

Florian, thank you for the update. I didn't even realize I could propose an edit to the page without opening a bug ticket. 
I'll be sure to take that route in the future!
